It's not that they shouldn't be correct it's that people are expected to do the job of multiple people with limited budgets so they contract their work out to services or don't take the time to double check stuff.
When I worked with the marketing people ot was a team of 3 that had to cover the US mexico and Canada, so they would have people on retainer to make things like art or text for a lot of the stuff, but I can see how they could use a service that used ai for those things
Look at what happened with Wacom, so I just see this kind of cost cutting is appealing to businesses that want to cut costs at the expense of quality

Again I'm not saying it's good but there is demand for this stuff as shitty as it is
The bad guy is the dude who made a hole
